SPECIFICATION forming part of Letters Patent No. 520,516, dated May 29,1894.

T0 at whom it may concern.

3e it known that I, THOMAS J. GLEARY, a citizen of the United States,residing at Westfield, Hampden county, and State of Massachusetts, haveinvented a new and useful Bufiing-Wheel, which was described in myoriginal application for patent for buffingwheel, filed June13, 1893,and serially numbered 477,425, of which this application is a division.

The following is a full, clear, and exact specification.

ll/ly invention relates to improvements in pollshing or buffing wheelsparticularly of that class which are built up of disks of suitablesubstances, and consists in building up a wheel of disks of cloth andpaper and the novel arrangement of said disks which are secured togetherin the wheel.

The objects of my invention are to construct a very strong andserviceable bufiing wheel which will present a very hard and strongcutting or polishing surface and that will readily hold rouge, or otheragent that may be applied to the periphery of the wheel, to assist it inthe act of polishing.

My invention is illustrated by the accompanying drawings, in which-Figure 1 is a perspective side elevation of a series of paper disks usedin the wheel, the fibers of the paper of the several disks beingindicated by the dotted lines, and Fig. 2 is a cross section through thecenter of the buff- 1ng wheel of my improved construction, the clothdisks being indicated by the darker shading.

Similar letters refer tosimilar parts throughout both views.

A A are disks of paper. The paper used by preference in this wheel is aheavy rope manila.

. B Bare disks of any suitable fabric, for instance, cotton cloth, ormuslin.

My invention consists in placing the several disks of cloth against eachother, then placing several disks of paper upon the disks of cloth, andso on, as shown in Fig. 2, in which the cloth disks are indicated by thedarker shading and the paper disks are indicated by the lighter shading.

It will be observed by reference to Fig. 2

that there is a predominance of paper used in the construction of thewheel, the purpose of which will be hereinafter explained.

D D are suitable pins or rivets which are passed through the severallayers of cloth and paper, and headed or otherwise fastened on bothsides of the wheel to hold the various layers of cloth and paper tightlytogether.

The main feature of my invention, and the one feature which makes awheel built up of disks of paper and disks of cloth in the above manner,practicable, is the important arrangement of the paper disks.

It should be mentioned that any paper having a sufficiently marked andheavy fiber can be used to great advantage in this wheel.

In placing the disks of paper in this wheel, it is necessary that thefiber of the paper of the several disks shall run in substantially thesame direction.

I am aware that wheels have been built heretofore of disks of paper andcloth, but this important feature, of placing the fiber of the severaldisks of paper throughout the wheel in the same direction, has neverbeen appreciated and its value known.

It has .been practically demonstrated that a wheel constructed of clothdisks and paper disks, as above described, in which the fiber of theseveral disks of paper run in various directions,-that such a wheel isthoroughly impractical, the periphery or cutting surface of the wheelofiering no distinct grain. The periphery of such a wheel will almostinstant- 1y, upon being revolved against any hard substance, fray out,soften and become'useless. On the contrary, it has been practicallydemonstrated that awheel built of exactlythe same material and of thesame number and size of disks of cloth and paper, when arranged as abovedescribed, with the fiber of the paper all running substantially oneway, will instantly cut and polish the hardest of metallic substanceswithout fraying or becoming soft. A wheel thus constructed, in which isinter= posed occasional disks of cloth will more readily hold rouge, orother polishing agent which may be applied to the periphery of I thewheel to facilitate the act of polishing, than a wheel built entirely ofpaper.

Having thus described my invention, what all secured together,substantially as and for the purpose specified.
